Referring more specifically to the drawing the numeral I0 denotes a suitable base member upon which are mounted end plates II, one of which is shown and described, there being another similar plate disposed on the other sideof the machine. Secured to plate II, as: by screw I3, is a block I2, and secured to block I2 as by screw I5,is another block I4. Block I 6 is-also secured to the side of plate II as by screws I'I andto block I6 is secured another block I8 by suitable screws I9. Members I2, I4, I6 and I8 are provided to support the second selector bars to be presently described.

Secured to block I8, as by screws 26, is a bracket 25 which supports an electro-magnet 21 which is adapted to be energized successively from any suitable impulse transmitting .apparatus such as the scanning mechanisms shown in my co-pending applications, Serial lgumbers 404,331 and'517,171, said impulses being"transmitted from the scanning mechanism through wires 28 and 29.

In Figures 1 to 6, the structure of said second copending application is shown in part,.such as side plate II, pin shafts I04 and I60 with slight. 'modifications, and though the other side plate is not shown, it is present for supporting the'other ends of the pin shafts I04 and I60.

The entire selector apparatus is driven by a shaft 30, which has one end rotatably mounted in bearing 3|, said bearing 3| being secured to frame II by any suitable means such as stud bolts 32, and the other end of shaft 30.18 rotatably mounted in a suitable bearing in the other side wall member not shown. Fixedly secured on shaft 30 is a suitable pulley 33 which is constantly driven from any suitable source of power not shown. A gear 34 is also fixedly mounted on shaft 30', which gear meshes with anotheridler gear 35 rotatably mounted on stud 36 fixedly securedin sidewall member II. Gear 34 rotates in a clockwise direction as seen in Figure 2, which, in turn, rotates gear 35 in a counterclockwise direction. other gear BI which is fixedly secured on shaft 42 and this gear GI is caused to rotate in a clockwise direction. V

Gear 4| meshes with another gear 43 which is secured on shaft M, and gear 43 also meshes with another gear 45 secured on shaft 46 which also has pinion Ma which meshes with pinion 461) which is similar to clutch disk 52 in my co-pending application Serial Number 517,171 which, in said application serves to return the carriage in the scanning mechanism to starting position. Gear 65 meshes with another'gear 41 which is fixedly mounted on rotatable shaft 68, said gear 37 being integralwith disk 89 which supports one end of the selector rods in the first selector, which is similar in structure to first selector shown in my co-pending application, Serial Number 517,171. It can be seen, by referring to Figure 2 that since gear 4| rotates in a clockwisedirection, gear 43 will be rotated in a counter-clockwise direction. This rotation will cause gear 15 to be rotated in a. clockwise direction which, in turn, will rotate gear 57 in a counter-clockwise direction, and therefore, the first selector will be Gear 35 meshes with anrotated in a counter-clockwise direction as will be noted by the arrows on the drawings.

One end of shaft 48 is rotatably mounted in sidewall member II, and this shaft extends laterally and has its other end rotatably supported by arm 50, integral with block I4. Another disk 5I is fixed on shaft 48. Slidably mounted in disks t9 and 5! and frictionally held against unaided sliding movement by springs 5Ib in bores 5Ia, are

selector rods 52, 53, 54, 55, 56, and 51, and each of these rods have fixedly secured thereto selector one end of each rod projects but beyond the edge of the disk 5| toward the observer when they are not moved by cam lever 'II controlled by impulses from the scanning mechanism.

A suitable cam I5I is secured to member I0 and is disposed around shaft 48; This cam has a projection I5Ia which is adapted to be' contacted by the ends of the selector rods which restore them to their normal position.

Disks 49 and SI, at the places where they are penetrated by rods 52 to 51 have radial bores. 5| a therein, in the bottom of which there is a compression spring- 5I6 which presses against the have been moved by cam lever 'II to successively rods and holds them frictionally in whatever position to which they are moved.

The cam lever II is pivotally mounted intermediate its-ends to block I4 by any suitable means such asbolts I2, anda weak tension spring I3 is connected to the right-hand portion of cam lever II as'seen in Figure 1, and normally holds it in 76 a. position, shown in Figure 1. The tension of spring 13 is not suflicient to move slidable rods 52 to 51, but slides over their ends when not enengaged by a hook member 14. Hook 14 is normally held against member 15.

Member has pivotally secured thereto an arm- 15 which is normally pressed away from magnet 21 by compression spring 19. Loosely mounted on a pin 16, near the end of arm 15, is dog member 14 having a shoulder near its outer end and this dog member is'also penetrated by a suitable pin mounted in arm 15 and around which, a compression spring 11, is mounted, which normally presses the lower end of dog 14 against arm 15. This allows a resilient connection of arm 15 and dog 14. When magnet 21 is not energized by an impulse, the parts will be in a position as shown in Figure ,1, that is, tension spring 13 will pull the right-hand end of cam lever 1! back to a point where it will fall behind the hook on. the end of dog 14 and the spring 19 will force dog 14 to the position shown in Figure 1.

. This will latch the cam lever 1| in position and cause the next sliding rod in the first selector, which crosses the left-hand end of cam lever H, to be moved laterally by the cam lever H. The impulses for operation of magnet 21 may come from any suitable source such as the scanning mechanism shown in my above referred to copending applications, or it could come from a perforated tape or any other suitable impulse transmitting means.

In order to selectively rotate pin shaft I04, permutation bars 81, 88, and 89, forming part of the second selector, are provided, which bars are slidably mounted in blocks I2 and I4 and are operated by the first selector. 81 is provided to operate the rack selecting mechanism. This bar 81 has suitable upwardly pro-'- jecting members 90 and 9| between which a suitable projection 93 is adapted to operate. Projection 93 is fixedly secured to the lower portion of member 94, said member 94 being mounted for oscillation as at 95. upwardly and has a fork .94a therein, adapted to engage a pin 96, integral with a laterally sliding member 91.

Since member 94 is pivotally secured to a vertically disposed slide 98, as at 95, it is evident that when a'lug on rod 10 pushes permutation bar 81 to theright, as shown in Figure 7, that the lower end of bar 94 will also move to the right which, in turn, will move the upper end of bar 94 to the left. This movement of the upper end of bar 94 to the left, will cause pin 96 and sliding member 91 to move to the left and will thereby move rack I02 upwardly and rotate pin shaft I04 in a 'clockwise direction.

By referring to Figures 11 and 20, the means for reversing the movement of the racks can be seen more clearly. Member 91 is slidably secured to vertical slide 98 by means of a suitable cuff 99, said end being secured to slide 98 by any Permutation bar This memberv 94' projects of member 94 will then force pin 96 and sliding bar 91 to the left. This will cause bar 91 to engage rack I02 and at the same time release rack IOI which will allow pin shaft I04 to be rotated in a clockwise direction. It is evidentthat the amount of distance that the slide is allowed to move upwardly, and also the position of sliding bar 91, determines the amount and the direction of the rotation of pin shaft I04.

' Slide 98 is normally pulled upwardly by means of a spring I06, said spring being secured at its lower end as at 95, and at its upper end to bracket I08,said bracket I08 being secured to transverse bar I09. Bar I09 is secured by any suitable means such as screws IIO, to guide members H2 and also to bearing II3.

Bearing H3 is mounted in sidewall member I I, and this bearing holds the racks and also the vertical sliding members in position. Each time the selector barrel makes a revolution, the slide 98 makes one upward sliding movement, the amount of stroke of this movement being determined by permutation bars 88 and 89, one, or both of which, may have been moved by the se- .lector rods in thecontinuously rotating first selector.

On the upper end of slide 98 is a roller II4 which is eccentrically and fixedly mounted on bolt H5, in order that adjustment between this roller and cam I01, which is fixedly mounted on shaft 42, may be obtained. Each time that the slide moves upwardly, the cam I01 returns it to its lowermost position during the same revolution of the selector barrel.

The sliding bar 91 remains in its laterally moved position and returns the rack it engages to normal position under pressure of'cam I01. This normal position is shown in Figure 2. The next selection determines whether 91 remains in engagement with rack IN, or is shifted to engage x rack I02.

The normal position of members 98 and 98' is wardly under pressure of springs I06 and I06 depending upon which of the permutation bars,

controlling upward movement, are actuated by the first selector. Also the direction of rotation of the pin shafts I04 and I60 is determined by the permutation bars 81 and 81', as has been fully described. The purpose of cams I01 and I01 is to return the members 98 and 98 to lowermost position to permit reset of the permutation bars by the reset arm I40, and reset the third selectors I04 and I60.

Secured to the lower portion of slide 98 by any suitable means such as screws I2I, is another member I20. Member I20 has vertically disposed projections I22 and I23 integral therewith, which project upwardly, and integral with the lower side of permutation bar 88 are projections I24 and I25 which project downwardly and are disposed opposite projections I22 and I23 when permutation bar is in normal position.

It will be seen by referring to Figures 8 and 20, that there is a clearance between projections I22 and I24 and projections I23 and I25. This clearance will allow a slight upward movement of the slide 98 each time the selector barrel makes a revolution, regardless of whether any impulse has actuated any of the slidable racks in the first selector.

Permutation bar 88 is slidably mounted in transverse groove 88a in slide I26 which, in turn, is mounted for vertical sliding movement in block I2. Slide I26 is normally held in elevated position by means of a spring I2'I which is secured to the lower side of block I2.

The lower side of'slide I28 has a projection I26a which is adaptedto engage the lower side of member I20. The side of slide I26, nearest the observer, in Figures 9 and 20, is vertically grooved which forms projections I29 and I30, and these projections extend upwardly to near the lower side of permutation bar 89. When per- 'mutation bar 89 is moved to'the right in Figure 4, by one of the selector lugs, the projections I29 and I30 are adapted to move upwardly into notches I3I and I32 cut in the lower side of permutation bar 89, when cam I01 allows spring I06 to move bar 98 upwardly.

In the position shown in Figure. 9, a small clearance is apparent between the lower side of per .each revolution of the selector barrel, a sufiicient amount to allow the pin shaf to be rotated and to bring the first row of pins either above or below to a horizontal position, depending on which rack, IM or I02, is engaged by bar 9l. These clearances are cumulative, and therefore, the slide 98 will be allowed to move upwardly the combined amount of both clearances, each time the selector barrel makes a revolution. The position shown in. Figure 13 is the normal position of the pin shafts to which they are returned by members 98 and 98'.

Whenever permutation bar 88 is moved inwardly by one of the selector lugs, the slide 98 and the lug I20 on the lower end thereof, will beallowed to, move upwardly, past the projections I24 and I25, until projections I22 and I23 strike the lower-side of permutation bar 88 between projections I24 and I25. In the meantime, the slide I26 will be held in the position shown in Figures 8 and 9.. This upward movement will bring the third row ofpins in the pin shaft in a horizontal position.

A spitable leaf spring 82 is secured to permutation bar 88 by any suitable means such as screws 83. This spring is adapted to contact slide meniber I26 and to assist in frictionally holding the permutation bar in whatever position it may be moved.

By referring to Figures 9 and 20 it can be seen that when permutation bar 89 is pushed inwardly by one of the selector lugs that projections I29 and I 30 will be allowed to move upwardly into notches I3I and I32 which will allow the slide I28, bar 88, member I20 and slide-98 to move upwardly a like amount. This upward movement will bring the second row of pins in the pin shaft in a horizontal position. I

If permutation bars 88 and 89 are pushed inwardly at the same revolution of the first selector,

the slide 98 will be allowed to move upwardly the combined amount described in. the two preceding paragraphs and this upward movement will bring the fourth row of pins in the pin shaft in a horizontal position. .Therefore, four combinations have been described thus far, namely, when the tween the projections I22, I 23, I 24, and I25 combined with the clearance getween the projections The four combinations above described, are obtained by the rotation of the pin shaft in one di-a motion, and it is evident that four other combinations may be obtained by having bar 8! select the other rack, to rotate the pin shaft in another direction, thus giving eight selections for each pin shaft.

The above description appliesto the mechanism which operates the front pin shaft I04. The rear pin shaft I60 is operated with an identical structure and similar reference characters will be given with the prime notations added.

The right-hand end of permutation bars 81, 88, and 89, as shown in Figure 4, are adapted to abut the left-hand end of sliding bars I35, I36 and I31 which are slidably mounted in block I8.v The right-hand end of bars 835, I36, and I31 are adapted to be contacted by 'members I39, thread ably secured in reset arm I40.

Reset arm I40 projects upwardly and is mounted for oscillation as at MI and on the upper end of this member, a suitable roller I42 is secured which is adapted to contact cam I43 mounted on shaft 30. Each time shafts 30 and 08 make one revolution the lower end of the member I40 is forced inwardly since cam roller I42 contacts cam I43 at all times. A suitable spring I44, which is secured to the lower edge of member I40 and also to member II, holds the cam roller I42 against cam I43 at all times. bers I39 return the permutation bars to normal position each time a revolution of the selector barrel is made,v and after a selection has been made, so' the selector is reset for receiving another selection from the first selector.

It is to be observed inFigure 2, that the sliding bars 98 and 98' have been returned to normal position, while the high point I43a of cam I43 has also operated lever I40 to move the second selector bars back to normal position ready to receive the setting from the first selector as it is to be observed must be returned to normal position beforesec- In other words, the memthat rod I0 is almost in position to move past the. second selector bars. It is evident that 98 and 98' 0nd selector bars 88, 89, 88', and 89'. can be recorresponding to I04 and I in the application, 5

is at a position where no pin in the first pin shaft is coinciding with a push bar, and no pin in the second pin shaft is in position to be operated,

but in the present application, the pin shafts I04 and I60 are always returned to a position where one pin therein, in both the lower case and highercase sections will be in operative position. This is caused by the clearance between the bars 88,

189, 88', and 89' and the projections I22; I23, I29,

and I30, already described, which allows the memthe second selector bars are moved. Since bars 81 and 81 are always returned to normal position, then slide 91 is always in engagement with rack IOI before this upward movement is allowed in 98 and therefore, the pin shafts I 2 and IE0 are always moved slightly ina counter clock-wise direction upon upward movement of 98 and 98' due to this clearance to position the first pin in both sections of the pin shafts in an operative msition. This means that when no impulses are received by the magnet in one revolution of the first selector that the pin shafts will be in a position to operate the carriage return mechanism, as shown in my co-pending application, Serial Number 517,171, or for other purposes.

For the operation for the rear pin shaft I60, suitable bars M5, M6, and M1 are slidably mounted in member I 2 and the right-hand end of these bars, as shown in Figure 4, contact permutation bars 01, 88' and 09, these bars being identical in all respects to permutation bars 81, 88 and 89.

A suitable plate 80 is secured to the upper portion of block it by any suitable means such as screws 00a, which serves to hold permutation bars 81 in its lower position and prevent it from rising upwardly. A similar plate IIG is secured to the upper portion of block IZby any suitable means such as screws IIBa, which also serves to prevent upward movement of bars 98, I45, I486, and I41. Another plate 1 is secured to block it by any suitable means such as screws II1a which prevents the upward movement of bars I35, I36, I31

and permutation bar 81'; whereas plate II 8 is secured to block I6 by any suitable means such as screws Ba and this plate prevents the upward movement of permutation bar 89'. As heretofore stated, there is a possibility of eight combinations being set up by the first three permutation bars, namely, 81, 88, and 89, but when these bars are worked in conjunction with bars 81', 88', and 09' and the mechanism associated therewith, there is possibility of sixty-four combinations being set up for selecting sixty-fourwork-performing instrumentalities. This number of selections is increased by the split pin arrangement to be hereinafter described. 7

Pin shaft I 0d has slidably mounted therein a plurality of pins which are radially disposed at different angles in the shaft and when they are brought to a. horizontal position they are adapted to be pushed inwardly by suitable striking bails I51 or. IS'Ia, which are identical to the striking bails 160 and 112 in my co-pending application Serial Number 517,171, which in turn forces slid ing bars I52, and the split bar such as I50 and I58, to theright as shown in Figures 3, 12, and 13, to move one of the pins which are slidably mounted in rear in shaft I60. The sliding bars I52 are more ful y shown and described in my co-pending application Serial Number 517,171, as bars 6201) to 8331). The right-hand end of the pins in pin shaft I 60 move members 669 pivoted at 616, to move one of the members 618 into the path of a striking bail 100 to cause movement of one of the work performing instrumentalities such as 30a. The parts 659, 615, 618, and 100 are fully described in my co-pending application Serial Number 517,171 by identical reference characters, and 30a bears reference character 30 in my copending application:

' The bars between'the front and rear pin shafts are shown in normal position as in Figures 3, l2, and 13, and are held in this position by means of compression springs I63, 'one end of which is adapted to press against a plate I60 and the other end presses against projections I 65 which are integral with the lower side of the sliding bars.

Front pin shaft I0 has a lower housing I61 and an upper housing I66, both of which are semicircular in cross-section and serve to keep the pins in their proper position with the housings. The rear pin shaft I60 has similar housings I68 and IE9 which answers the same purpose and holds the pins in their proper position. a

Pin shaft I04 is similar to pin shaft SDI in copending application Serial Number, 517,171 and has a plurality of pins 200, 20I, 202, and 2M and the like, identical to the pins 650 in said copending application. The pin shaft I60, similar to pin shaft BM in said co-pending application, Serial Number 517,171, has a plurality of pins IGI therein, corresponding to pins 650 in said second co-pending application. The entire length of the pin shafts is not shown in the present application, as this is shown in said second co-pending application. The portions of the pin shafts having the split pins therein are shown in this application, as well as adjoining portions.

Dual means are provided in a portion of the second selector which not only operates to control rotation of one of the pin shafts but also to determine what portion of the pin shaft has its pins moved for selection of a character.

In order to obtain additional characters for fractions and the like, it has been necessary to provide additional mechanism in the third selector or pin shaft. The object of this mechanism is to make it possible, when associated with a line-casting machine, to operate the lower case side of the machine from selections made on the higher case side.

Integral with the upper portion of sliding bar I45, (see Figures 2 and 4), is an upstanding projection I10 which has in the upper end thereof, a suitable pin I1 I. This pin is adapted to operate in a slot I12, in the lower end of vertically disposed member I13, mounted for oscillation as at The upper portion of member I13 has beveled surface I15 which is adapted to contact roller I16, said roller I16 being disposed on one end of rod I11. Rod I11 is slidably mounted in sidewall member II and also in bracket I18, and has fixedly secured thereon levers I19 and I80. Lever I80, (see Figure 12), has a downwardly projecting member I8I integral therewith, to which is attached a suitable tension spring I82 and the other end of this spring is secured, as at- I83, to the upper portion of cover plate I84 which is fitted across the sliding bars. Spring I82 normally holds the roller I16 on the end of rod I11, against beveled surface I15 at all times.

Lever I19 has a downwardly projecting arm I86 integral therewith which is similar to downwardly projecting arm I8I and this arm is adapted to be contacted by lug I58a on sliding bar I58 when a suitable combination is set up.

It is evident by referring to Figure 3, that in the'position shown, it is impossible to operate the sliding bar I58 without operating the sliding or push bar I50,:sjince lug I 58a will push arm I86 to the right in Figure 13, which movement will be transmitted through rod I11 to arm I8I, which in turn will be pushed against lug 15011 on bar I50.

Let us suppose that selector lug 63 will be pushed away from the observer in Figure 4 and to a position where, as it revolves, it will contact and move sliding bar IE5. This will cause the upper portion of bar I13 to be moved to the left which will move rod III inwardly or away from the observer in Figure 1. Likewise, the arm II will be pushed away from the observer 'in Figure 3, and approximately half of this projection will be to the right of the lug I990. (Figure 3), whereas, the other half will beto the left of lug I59a, and in the meantime, projection I86 will be pushed out of the path of projection I58a. In this position both bars I99 and I59 will be moved simultaneously by pin 295. In the position shown in Figure 8 it is seen that when bar I 59 is moved it will move bar I59 through the instrumentality of rod ill to select a character from the lower case side of the pin shafts, y

In ordinary newspaper work, the linecasting machine used for setting the market reports is equipped with an additional magazine having a different font of type from that which is used in straight matter, for example, the miscellaneous characters such as fi, if and n, which are on the lower case side and the characters 82", and lb. which are on the cap side are removed from the magazine and fractions substituted in their particular channel, or other characters may be moved in the same manner and substitutions made. This additional magazinc is moved to operative position when setting market reports.

In the operation of this machine as shown in its present form, all of the fractions are operated from the cap side. When figures and fractiors aretransmitted over the wire they are received in this form, i. e., 88-6, 88-7, 8&5, etc., which denotes 88v 6/8, 88%, 88% etc. It is evident that the fractions 6/8, 4/8 or 2/8 represent /2 or in the magazine. The dash between'the 88 andthe 6, for example, when it is scanned, shifts the mechanism to the cap side and is equivalent to the cap shift signal which changes the operation of this automatic typesetting machine, from lower case to cap.

Since three of the fractions are on the lower case side, namely, and V operated by pins I99, I9I and I92 respectively, and must be operated from the ,cap side, the mechanism pre- I -viously described, is used to accomplish this result. While the channels in the magazine corresponding to split pins I99, I96 and I92 are accupiecf by fractions, there is no occasion for these particular pins to be operated from the lower case side; however; when these particular channels are occupied by characters-fl, K and h pins I9'I, I99, and I99 which are in the same vertical plane as pins I99, I9I, and I92 are brought into .action through the normal workings of the ma chine and are, operated from the lower case side. In other words, pins I99, WI, and I92 are for fractions operation only, in this particular case, and pins I97, I99, and I99 are for use in normal operation of the machine.

By referring to Figure 3 the pins are shown which operate the fractions. Split pins I99, MI, and I92 operate fractions /8, 3'8 and respectively, and on the lower case side, while pins I93, I99, I 95,'and I96 operate fractions and respectively, and are on the cap side.

- All fractions set up are operated primarily fromsectional pin'roll I99 through pin 299 or 29L Pin 299 operates the fraction 7 and when this pin 299 is brought in'a horizontal line it contacts slide I590. which also pushes lever I95 to the right, slide I58 carrying lug I58a, (see Figure 3) This movement is transferred through shaft ill to lever IN, the lower portion of said lever engaging lug l59a which operates slide I59 to .push split pin I92 in the same direction. It

should be noted that slide I58 also'pushes bar I89 to the right at this time but since neither of pins I93 to I96 inclusive, are brought into line, no selection .is made from this point.

When pin 29I is brought to a horizontal posiclockwise direction, bringing into line one of pins I99 to I96 inclusive. The operation which causes pin roll I69 to operate in a clockwise direction also causes shaft Ill and lever I to move away from the observer, (see Figure 3), so that lug I58a. will not contact lever I86; therefore, either one of pins I93 to I99 inclusive may be operated from pin 29I which engages slide I59, which slide also engages bar I89 to operate the pins.

The provision of the split pin arrangement in pin shaft I99 and the means associated with rod I'I'I for operating the same, really amounts to a fourth selector, for it increases the number of work performing instrumentalities which can be selected from a given number of pins in each pin shaft. Although I have shown only one rod I'I'I, operated from one of the second selector bars, it is evident that each of the other selector bars in the second selector, could be likewise associated with a similar mechanism, which would likewise increase the number of selections possible from pin shafts having a given number of pins therein.

It is to be noted that in the second co-pending application, the pins are arranged so that their protruding ends form a spiral arrangement around the two pin shafts and this structure is present in the present application, though not shown fully, therefore conventional pin 295, for

example, operates in the usual manner to operate ment one of the split pins I99, I9I, I99, I99, or'

I99 will be operated. Each of these split pairs have one of their counterparts arranged in the conventional position, whereas the other counterpart is arranged in another angular position to be operated by the fourthselector arrangement. I

When the higher case striking bail I571; is operating it is evident that the pins I9I, I92, and I99 in Figure 3, even though they are alined with. the push bar I59, will not be moved, but by the split pin, or fourth selector arrangement, these pins are moved through rod Il'I being moved by the push bar I58 which-is operated while it is out of alinement with any of its associated pins I99 to I96, but moves the pins in the lower case side of the pin shafts.

In market reports the numerals such .as 2, 3, will be on the lower case side of the selectors I99 and I69, or the upper portion of Figure 1. The fractions such as f /s", /s will be on the higher case side, or nearest the observer in Figure 1, The quotation 6% would be transmitted aoemse as .to 6s, spaced from each other with some notation, such as the higher case shift code therebetween. The first f6 would be selected by the lower case side of the pin shafts, but the higher case code before the next 6 would shift the mechanism to the higher case side and move the higher case striking bail and the Second 6 would be as for reproduction by the typesetting machine, typewriter and the like. The pins for 6 and 6/8 or are located in the same horizontal plane in the pin shaft I60.

Pin 205 in the lower half of Figure3, is a conventional pin and when it coincides with conventional push bar I09, one of the pins I6I is normally operated as one of these pins Ifil is alined with push bar I59 and pin 205. This is a normal operation of the machine. When pin 202 is alined with the portion I89 of a conventional push bar, it always has one of the pins I93 to I 96 alined therewith, "and this is normal operation, but when one of the pins 200 or 20I is alined with bar I58 then none of the pins I93 to I96 is alined with bar I 89 but the lug i58a moves lever I 86 which in turn moves lever IKI against lug I50a and operates the usual split portion of pins 691, I98, and I99 or the conventional pins IISI, one of which will be in alinement with the split push bar I 50. This operation can take place without any shift of rod I11. Also it is seen that when a pin in pin shaft I04 moves push bar I50 this will operate the portion of the split pin bars coinciding therewith which are in normal position in pin shaft I60 and operate in the usual manner. Now when the rod I11 is moved laterally to cause interlocking of lugs I491]. and I50a, then it is seen that operation of 'splitpush bars I49 and I50 will take place but these will not coincide with the pins I6I but push bar I50 will coincide with some of the unusual counterparts of the split pin opposite thereof and will I operate these split pins for selecting a character ,on the lower case side from operation of the any of the pins I93 to I96 but the rod I11 will be moved which will move one of the split pins opposite push bar I50 when the parts are in the position as shown in Figure 3.

It is therefore evident that a plurality of selectionscan be made by employing a portion of the other section of the pin bars when one of the sections is being operated by its striking bail.

The selections made through the operation ,of pins 200 and 2!", and the push bars I49 and I50 are transferred over to the lower case side of the pin shafts Without the shifting of therod I11, and with the use of rod I11 it is seen that operation of push bars I 49 and I50 is effected one at a time or together, depending on whether or not the rod I11 is shifted.
